Final initialization for constructors This function is called at the end of generated constructors to allow the specification writer to add special initialization functions or tests. Default is to do nothing. Otherwise it should be overridden in the spec file, in NewHeaderCode/NewOutlinedCode.

For Fortran. When called from a node of any other language, behavior is undefined (see SageInterface::is_Fortran_language). Returns a bool value which is true if the current expression is "almost definable". "Almost definable" here means as defined by the Fortran standard (2.5.5), with the caveat that allocatable variables are always called an lvalue. The Fortran standard dictates that an allocatable variable which has not been allocated is not definable. In the general case, it cannot be statically determined whether an allocatable variable has been allocated or not. Note: constants in Fortran are not lvalues, while in C and C++ lvalues may be const.

Some expressions store internal SgType pointers explicitly while others compute them from other expressions. This function is true if it has a data member that is a type (pointer, array, etc.). More...

Member Function Documentation

This function clones the current IR node object recursively or not, depending on the argument.

This function performs a copy based on the specification of the input parameter. The input parameter is used to determin which data members are copied by reference and which are copied by value.

Parameters

help

- If this argument is of type SgTreeCopy, then the IR node is cloned recursively. If its of type SgShallowCopy only the first level of the IR node is copied, everything else is left pointing to the the original IR node's object's data members.

FORINTERNALUSE This is used in internal tests to verify that all IR nodes are allocated from the heap.

The AST File I/O depends upon the allocation of IR nodes being from the heap, stack based or global IR nodes should not appear in the AST if it will be written out to a file and read back in. To enforce this concept, this function implements a test to verify that the IR node can be found on the heap and is part of a larger test of the whole AST. This test must pass before the AST can be written out to a file. This is part of a compromise in the design of the AST File I/O to support binary streaming of data to files; for performance. It is also rather difficult, but possible, to build a useful AST with IR nodes allocated on the stack or frm global scope, this test filters out such cased from being used with the AST File I/O mechanism.

FORINTERNALUSE Returns STL vector of pairs of SgNode* and strings for use in AST tools

This functions is part of general support for many possible tools to operate on the AST. The forms a list of ALL IR node pointers used by each IR node, and is a supperset of the get_traversalSuccessorContainer(). It is (I think) less than the set of pointers used by the AST file I/O. This is part of work implemented by Andreas, and support tools such as the AST graph generation.

Warning

This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

FORINTERNALUSE Processes pairs of references to SgNode* and strings for use in AST tools

This functions similar to returnDataMemberPointers() except that it passes references to a handler object. As a result there is FAR more damage that can be done by using this function, but it is type-safe. This is provided for support of internal tools that operate on the AST, e.g the AST Merge mechanism.

Warning

This function can return unexpected data members and thus the order and the number of elements is unpredicable and subject to change.

FORINTERNALUSE Returns a unique index value for the childNode in the list of children at this IR node.

This function returns a unique value for the input childNode in set of children at this IR node. Note that a negative value indicates that the input node is not a child. This is the basis for the implementation of the isChild(SgNode*) member function. Data members that are NULL in the IR node are counted internally (so that this function returns value that could be statically defined, and so are not dynamically determined).

Warning

The mapping on children to integer values could change from release to release of ROSE.
